BUTTON.

T0 all whom z't mag c0npem Be it known that I, STEIHEN A. GLYNN, a citizen of the nited States, residing at Antigo, in the Stute 0f WVisconsin, have invented certain new and useful Improvements in Buttons; and 1 do hereby declare that the following is a full, dem, und exa ct desc1iption 0f the invention, such es Will enable others skil1ed in the a1t to which it appartains to make end use the same.

The present invention has relation to improvements in buttons und more particularly uppertains 130 the detachable type 01 garment fasteners.

The principal object of the invention is to provide a, button of sectional construction, adapted f01' detaehable connectlon t0 a garment and Wherein the button elements hzwe interlocking engagement one with the other.

A further object is to provide a device of the chamcter set forth that is capable of adjustment, to separate the interlocking arts :t?or detachment fron1 the germeniu.

1Vith the above und other objects in view Which Will hereinafter appear as the description continues, the invention consists 01 the novel fcatures o1": construetien, combinetion und formation of parts as Will be hereinafter more fu1ly described zmd particularly pointed out in the appended claim.

In the aceompanying dmwings has been shown a simple and preferred form of the invention, it being, however, understood that 110 limitation is necessarily made to the precise structufal details herein exhibited, but the rignt is hereby reserved t0 zu1y changes, altemtions 01 modifications t0 Whieh recourse may be had that come within the .scope 01' the elaim without departing from the spi1it 0f the invention 01' sacrificing the eificiency of the same.

The invention has been illustrated in its preferred and modified embodiments in the accompanied drawings, wherein,

Figure 1 is an elevational view of the preferred form of button;

Fig. 2 is a bottom'plan view 0f the same;

Fig. 8 is a, disassembled elevational view;

Fig. 4 is a plan elevation 01 the base element of the button;

Fig. 5 is a plan elevation of the spring member with the base shown diagrammatically;

Fig. 6 is a transverse sectional view of the Specification of Letters Patent. Patented May 18 1920 Applieation filed November 20, 1919. Seria1 N0. 339,515.

Fig. 7 is a similar view with the shank in locked position in t-he base.

Inearrying out the present invention, reference being had t0 the drawing in detail, there 1s provided a button comprising a hol- 10W annular base casing and a solid head sect1on. The base casing is of sectional comstruct1on, being formed of upper and lower plates 10 and 11. In the formation of the upper p1ate 10, the meta1 is struck in such n1anner as t0 provide a centrally disposed flat annular portion l2 and the depending alls of seid platze l0extend downwardly 1n concave-convex continuity whereby die lower peripheral edge 13 of the same Will engage the inner surface of' the lower p1ate 11. The lower plate 11 has its outer margmul edge portion 14 be'nt or lapped over the edge portion 13 of the upper plate and the seid elements at this point are he1d together. The upper plate 10 is provided at its central pa1t with a rectangular opening 15, und the lower plate a1; its central part is pressed outwardly 130 form an embellishment 16. Y

The flat annular portion 12 0f the upper platze section 10 is formed with the rectangw lau opening 15, and likewise the metal et this point is indented 0r notched at the opposite sides 01' seid opening 15 to form the upwardly projecting ridges 17. These ridges 17 extend at right angles to the seid rectangu1ar opening or s1ot 15 and maywith the seid epening be mde at one operation.

The t0p section of the i1nproved button comprises the fiat annular head 18 and shank 19, the 1ower end of the latter being formed with a restricted portion 20, Which is expanded into a substantially wedge-shaped lug 21, the inwardly tapering chisel edges 22 01 v vhich are gradually rounded. T he shank 19 immediately above the restricted portion 20, is swelled outwardly as et 23 t0 approximately the same width in cross section, es at the upper widest part of the wedge shaped 111g 21.

VVhen plates 10 and 11 are assembled, a spring platze 24 is disposed within the hollow interior of the p1ate l0and has its opposite ends curved downwardly. The edge portions 25 of the platze 24 engage the inner surface of the lowe r plate 11, while the curved portions of the pla,te 24 will engage portions of the upper plate at the intersecting point f the inner sind outer curves 0f the Wall 0f the upper casing platz: 10, so that a certain degree of resiliency is imparted t0 the central part of said plate at which point it is formed with a bearing notch 26.

The t0p section of tl1e button is connected to the casing 10, by adjusting shai1k 20 in such nmnner that the Wedge 1ug 21 is in register with the st 15, then forcing down upon the head 18, theriaby seating the lug 21 within the spring plate notch 26, und forcing said plate downwardly. The top secoion is then turned, a1; whiqh time the lug is below the annular flat surface 12, and consequently the shoulder s 27 of the lug 21 Will sat within the notches foimed by the iidges 17, being upwardly tensioned by the spring plate 24;.

It is obvious, that to detach the button sections of this form, it is 0n1y necessary t0 push inwardly upon ehe t0p section, revolve ths same until the lug 21 is moved into registrati0n with slot of the plae 10 and then lift up und remove t he said top section.

Having thus fu1ly described my invention,

what I clain1 as new und desire to secure by Letters Patent is:

- As a, new article of manufacture, a sepa- 1ab1e button comprising upper and lower interlocking sections, said upper section having a heacl and shank, said shank provided with a restricted portion expanding into a wedge-shaped Ing, said lower section comprising uppe1 und lower plates connected together t0 f01n1 a hollow -asing the upper o1 said p1ates formed with a raised annular portion having a rectangular opening therein, said annular poTtion provided with notches extending ab right angles 130 said opening, a spring p1ate arranged within said 110110W casing und having its opposite ends curved downwzmrdly, the end portions of said spring plate engaging thelower casing p1ate und the curved portions of said spring platte engaging said upper casing plate said spring platze being indented: -at its cent1al pa1t for the reception 0'f bhe said Ing and adapted for tensioning said shankluginto notches 0f themised annulan portion 015 the said cas ing.

In witness whereof I have hereunto sei; niy

band.
